Matrix.Equal Method (TMtx, double)

Compares two matrices.

Pascal

function Equal(const Mtx: TMtx; Tolerance: double = 0): boolean; overload;

Compares Mtx with the calling matrix and returns true if the matrices are equal (if all elements match in position and value). Tolerance defines the comparison tolerance. The maximum difference between elements may not exceed: +/-Tolerance. If Tolerance is omitted, a direct comparison algorithm is used.

Example

var A,B: Matrix; c: boolean; begin A.SetIt(2,2,false,[1,2, 2,4]); // 2x2, real matrix B.SetIt(2,2,false,[1,2, 2,4]); // 2x2, real matrix c := A.Equal(B,1e-8); // Check for differences bigger than 0.00000001 c := (A = B); // Check for an exact match end;
